Description

Technical Field

[0001] This utility model relates to the field of cutting technology, specifically to a moisture-retaining paper cutting device. Background Technology

[0002] With the digital transformation of cigarette manufacturing enterprises, digital control of all aspects of production is needed. The emergence of new packaging models is accelerating the transformation and upgrading of digital technology in cigarette making equipment. Among them, high-end products include moisture-retaining film, or moisture-retaining paper for short. The investment and use of moisture-retaining paper is currently a major trend in high-end product packaging. There are currently two main types of moisture-retaining paper in use: one is customized in advance by auxiliary material manufacturers according to product specifications, with dedicated film for specific purposes, which is more expensive; the other is used without molds, rolled up, and then cut with a cutter at the cigarette packaging factory. This type has lower costs and larger production scale.

[0003] When using rolls of insulating paper, the rolls need to be cut and packaged, such as... Figure 1 As shown, with color mark 1 as a reference point, the cutter needs to cut the moisturizing paper at a fixed position to ensure the opening position of the moisturizing paper pull tab 2 for packaging the moisturizing pack, so that each pack of cigarettes can be opened in a fixed position. The cut moisturizing paper will package the cigarettes into a moisturizing pack 3.

[0004] Existing fixed-cutting devices can cut paper rolls such as aluminum foil into rectangular pieces of uniform length for packaging. However, aluminum foil is a solid-color paper and only needs to be cut to a specific length without needing to be cut at a fixed position. In contrast, humidifying paper needs to be cut at a fixed position to ensure that the position of the humidifying paper pull sheet is not affected. Therefore, existing fixed-cutting devices cannot meet the requirements for fixed-cutting humidifying paper. In view of this, this utility model provides a humidifying paper fixed-cutting device.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] refer to Figure 2-4 As shown, this utility model provides a moisture-retaining paper cutting device, comprising:

[0032] The conveying channel 2 is a vertically arranged strip-shaped channel structure. In some embodiments, the conveying channel 2 is composed of two transparent plates, and the distance between the two transparent plates forms the conveying channel 2. The conveying channel 2, for the passage of dampening paper, includes at least an upper conveying section 2a and a lower conveying section 2b. A color mark sensor 3 is installed on the upper conveying section 2a. This color mark sensor 3 is located on the side of the conveying channel 2 and is used to detect... Figure 1 The color mark on the side of the Zhongbao desiccant;

[0033] The traction mechanism 5 is disposed between the upper conveying section 2a and the lower conveying section 2b. The traction mechanism 5 is used to traction and convey the moistening paper downwards so that it enters the lower conveying section 2b.

[0034] Specifically, in some embodiments, the traction mechanism 5 includes a first traction roller 51 and a second traction roller 52. Both the first traction roller 51 and the second traction roller 52 are rotatably mounted on the back plate 1 and are in contact with each other. Preferably, both the first traction roller 51 and the second traction roller 52 are rubber rollers. The sizing paper is conveyed downward between the first traction roller 51 and the second traction roller 52 by the rotation of one of the traction rollers. A pulley 16 is provided on the first traction roller 51 or the second traction roller 52, and the pulley 16 is located on the rear side of the back plate 1.

[0035] A cutting mechanism 6 is located at the bottom port of the lower conveying section 2b, and the cutting mechanism 6 is used to cut the moistening paper;

[0036] Specifically, in some embodiments, the shearing mechanism 6 includes a shearing roller 61 and a support roller 62. Both the shearing roller 61 and the support roller 62 are rotatably mounted on the back plate 1, and a blade 63 is provided on the shearing roller 61. When the shearing roller 61 rotates, the blade 63 contacts the support roller 62, so that when the dampening paper passes between the shearing roller 61 and the support roller 62, the rotation of the blade 63 cuts the dampening paper shorter. A pulley 16 is provided on the shearing roller 61, and the pulley 16 is located on the rear side of the back plate 1.

[0037] The traction mechanism 5 and the shearing mechanism 6 can be driven independently or synchronously. When driven synchronously, the two pulleys 16 are connected by a belt 18, and one of the pulleys 16 is connected to the output of the servo motor 17.

[0038] Two guide plates 8 are arranged vertically, with a gap between them. The upper guide plate 8 is fixed and located beside the conveying channel 2. An L-shaped baffle 14 is provided on one side of the lower guide plate 8. The L-shaped baffle 14 is connected to the output end of the paper receiving cylinder 15. Preferably, the paper receiving cylinder 15 is initially in the extended state, and its installation position is as follows. Figure 5 As shown;

[0039] In actual use, the sizing paper is conveyed downward in the conveying channel 2 and cut by the shearing mechanism 6. When the cut sizing paper meets the set phase requirements, it is judged to be qualified. At this time, the sizing paper falls on the L-shaped baffle 14. It is worth noting that the length of the sizing paper falling on the L-shaped baffle 14 needs to extend to the upper guide plate 8. When the cut sizing paper does not meet the set phase requirements, the L-shaped baffle 14 retracts, causing the sizing paper to fall without support.

[0040] The device also includes a toothed conveyor belt 9, which is located beside the guide plate 8. Preferably, the toothed conveyor belt 9 has a belt conveyor device and baffles are spaced on its conveyor belt. A smoke-pushing cylinder 10 is provided on the toothed conveyor belt 9. The smoke-pushing cylinder 10 has a push plate 11 at its push-out end. The push plate 11 is located on one side of the gap between the two guide plates 8, thereby pushing the cigarette box toward the gap. A fiber optic sensor 12 for detecting the arrival of the cigarette box is also provided on one side of the toothed conveyor belt 9. The fiber optic sensor 12 and the smoke-pushing cylinder 10 are electrically connected to the industrial control computer 7.

[0041] In actual use, the toothed conveyor belt 9 conveys the cigarette box forward. When the cigarette box reaches the fiber optic sensor 12, the fiber optic sensor 12 receives a signal and extends to trigger the cigarette pusher cylinder 10. After the cigarette pusher cylinder 10 is started, it pushes the cigarette box on the toothed conveyor belt 9 from the side to the moisturizing paper on the L-shaped baffle 14 through the pusher plate 11, so that the moisturizing paper adheres to the cigarette box.

[0042] In addition, the device also includes a back plate 1, on which a paper guide roller 4 is rotatably arranged. The conveying channel 2, traction mechanism 5, shearing mechanism 6, guide plate 8 and industrial control computer 7 are all arranged on the back plate 1. A support plate 13 is arranged on the back plate 1. The support plate 13 is located on both sides of the L-shaped baffle 14. The part of the support plate 13 located on the left side can extend into the lower surface of the toothed conveyor belt 9 to support the conveyor belt and allow the cigarette box to pass through the support plate 13 after the cigarette is pushed.

[0043] The controller 7 is used to receive signals from the color mark sensor 3 and control the traction mechanism 5, the shearing mechanism 6 and the paper receiving cylinder 15.

[0044] Specifically, refer to Figure 6 As shown, the controller 7 includes an encoder 71, a PLC module 72, an industrial computer 73, and a touch screen 74 connected in sequence. The encoder 71 can read the speed of the host, the rotation angle and speed of the servo motor 17, etc. The PLC module 72 communicates with the industrial computer 73 via an EtherCAT network cable. The color mark sensor 3 is electrically connected to the PLC module 72, and the output terminals of the PLC module 72 are respectively connected to a servo controller 75, a smoke push solenoid valve 76, and a paper receiving solenoid valve 77. The servo controller 75, the smoke push solenoid valve 76, and the paper receiving solenoid valve 77 are electrically connected to the servo motor 17, the smoke push cylinder 10, and the paper receiving cylinder 15, respectively.

[0045] The working process of this utility model is as follows: the damping paper enters the conveying channel 2 through the guide roller 4. During this process, the two traction rollers of the traction mechanism 5 pull the paper belt to continue moving downward. When the damping paper belt passes through the shearing mechanism 6, the blade 63 on the shearing roller 61 rotates to cut the damping paper. During this process, the color mark sensor 3 detects the phase of the color mark of the damping paper, and the controller 7 compares and judges the phase. If the phase meets the set requirements, it is a qualified product. The qualified damping paper falls onto the L-shaped baffle 14. At the same time, the cigarette box on the toothed conveyor belt 9 is pushed towards the damping paper on the L-shaped baffle 14 by the push plate 11, so that the damping paper can adhere to the cigarette box. If the phase does not meet the set requirements, it is a defective product. At this time, the paper receiving cylinder 15 retracts, so that the damping paper cannot fall onto the L-shaped baffle 14, thereby achieving the purpose of rejection.

[0046] Although the present invention has been described herein with reference to several illustrative embodiments, it should be understood that those skilled in the art can devise many other modifications and implementations that fall within the scope and spirit of the principles disclosed herein. More specifically, various modifications and improvements can be made to the components or layout of the subject matter arrangement within the scope of the disclosure, drawings, and claims. Besides modifications and improvements to the components or layout, other uses will be apparent to those skilled in the art.
